'rnnnrrroivn ATTACHMENT.

Application fiIedOetober 31, 1927. Serial No. 229 980.

' My invention relates to telephone attachments, and an ob ect is to provide a transmitting and rec .iving device in which the re ceiving member is always supported by the telephone standard without the necessity of removing it therefrom and holding it in the hand while talking over the telephone. As the result of this arrangen'lent, both hands oi the person who isusing the telephone are left free for the purpose of making memol'auda, consulting records, etc. in order to accomplish this result, I provide a receiving member which is carried by a tube through which sound impulses pass. l he tube is supported by a member pivot-ally carried by the telephone standard while a device connected with the pivoted member serves to establish and break talking communication with the receiving member according to the position in which the PlVOlJG(lII1HllJQ1' is placed.

The full objects and advantages of my in vention will appear in connection with the detailed description thereof, and the novel features of my inventive idea will be particularly ointed out in the claims.

In t e accompanying drawings whicl illustrate the application of my invention,

Fig. 1 is a side elevational view showing my device in its operative position and attached for use in connection with a telephone. Fig. 2 is a fragmentary view on an enlarged scale taken on the line 2-2 of Fig. 3 and showing the device in its inoperative position. Fig. 3 is a view in section on the line 8-3 of Fig. 1. Fi .lis a view in section on the line H of Fig. 1. Fig. 5 is a side elevational view of another form of the invention showing it in its operative position. Fig. 6 is a fragmentary view showing this latter form in its inoperative position. Fig. 7 is a view in section on the line 77 of Fig. 5. Fig. 8 is a view in section on the line 88 of Fig. 5.

In the embodiment illustrated in Figs. 1 to 4, there is shown a telephone standard 10 which carries a transmitter or mouth piece 12 and a hook 14. upon which is suspended a receiver 16. These parts may be of any well known or suitable construction. A supporting bracket 18 is secured to the standard 10 below the place oi attachment of the mouthpiece 12. The outer end of the bracket 18 carries a pivot 20 which extends through a lug 22 carried by an open-ended hollow member 2st which has a tubular extension 26 in which a section of tube 28 is adjustably held by a screw 30 passing through lugs 32 on a.

split portion 01 the exteusionZS. The outer end ot the tube 28 carries an ear piece 84. The open end ot a second hollow men'iber 36 is rotatably mounted on the open end of the holpositioned so as to extend out laterally, but.

when they are turned down into the position shown in Fig. 1. the lug assumes a positionunderneath the member 24 by which this lug is carried. The result is that since the pivot 20 is fixed, the member 24 will be lifted carrying the member 36 upwardly therewith. The member 36 has a tubular extension ll) in which a section of tube. 42 is adj ustably held by a screw 4st passing through lugs 46 on a split portion of the extension ell). The lower end of the tube 42 is secured in one end of a laterally deflected tube d8 the other end. of which carries a cup 50 which is positioned just underneath the diaphragm 51 at the lower end of the receiver 16 when the latter is supported by the hook 1a. A: strap 52 secured to the standard 10 carries a downwardly extending guide rod 5a which passes through an opening 56 extending out from the cup 50 whereby the latter is guided for up and down movement. When the tube 28 is lowered into the position shown in Fig. 1, the cup 50 will be lifted and thereby lift the receiver 16 sufficiently to permit the hook 1% to come up and establish talking communication in the usual manner which is Provided for establishing communication when the re ceiver is taken off the hook as is now customary. At the same time, the cup 50 closes the lower end of the receiver so that what is in effect a continuous tube is provided between the receiver and the ear piece for carrying the sound impulses to the latter. Upon loosening the screw 30 the ear piece 34: may be adjusted toward or trom the standard while by loosening the screw l i the cup 50 may be adjusted up or down so as to be properly positioned with relation to the lower end of the receiver 16. i y

In the form shown in Figs. 5 to 8, the customary receiver is dispensed with and a special receiver is provided. This receiver comprises a cup member 58 which contains a diaphragm 60. The cup 58 has acurved extension 62 into which the outer end of a tube 64 is fitted. The inner end of the tube 64 is adjust-ably secured in a tubular member 66 by means of a screw 68 passing through lugs 70 on a split portion of this tubular member. A cylindrical member 72 carries the member 66 as an extension thereof. The member 72 has a lug 74 through which a pivot 76 passes, this pivot also passing through the outer end of a su porting bracket 7 8 secured to the upper-portion of the standaid 10. A cam 80 extends out from the member 7 2 in such manner that when the tube 64 is in lifted position as shown in Fig. 6, this cam holds down an arm 14 which corresponds to the hook 14 so that in this position talking communication is shut oil'. When the arm 64 is lowered as shownin Fig. 5, the cam 80 moves off the arm 14 which is then free to rise so that talking eo1nmunication is established. An electrical connection 82 for the receiver extends through the cylindrical member 72 and through the tube 64 to the receiving member 58. It will be understood that in this form of the invention, sound impulses are transmitted through the tube 64 to the receiving member 58 when the latter is in lowered position while in the form previously described, sound impulses are transmitted through the tube 28 to the receiving member 34 when the latter is in lowered position. In both cases, sound impulses are cut off when the receiving mem her is in raised position.

I claim:

1. A telephone attachment comprising a support adapted to be secured to a telephone standard, a hollow member pivotally attached to said support, a tube carried by said pivoted member, a receiving member carried by the outer end of said tube, a second hollow member rotatably supported on said first hollow member for u and down movement therewith, a curve tube carriedby said second hollow member and having a laterally deflected end, and a cup member secured to said end deflected, said cup member being positioned beneath the customary receiver when the latter is supported by its hook and adapted to lift said receiver when said hollow members are moved upwardl 2. A telephone attachment comprising a support adapted to be secured to a telephone standard, a hollow member, a lug extending out from said hollow member and pivotally attached to said support, a tube carried by said hollow member, a receiving member carried by the outer end of said tube,-a second hollow member rotatably supported on said first hollow member for up and down movement therewith, a curved tube carried by said second hollow member and having a laterally deflected end, a cup member secured to said end deflected, said cup member being positioned beneath the customary receiver when the latter is supported by its hook and adapted to lift said receiver when said hollow members are moved upwardly, and a guide for said cup member secured to said standard.

3. A telephone attachment comprising a support adapted to be secured to a telephone standard, a hollow member pivotally attached to said support, a tube adjustably carried by said pivoted member, a receiving member carried by the outer end of said tube, a second hollow member rotatably supported on said first hollow member for up and down movement therewith, and a curved tube adjustably carried'by said second hollow member and having a laterally deflected end positioned beneath the customary receiver when the latter is supported by its hook and adapted to lift said receiver when said hollow members are moved upwardly.

In testimony whereof I hereunto affix my signature.

MAX SKOLNIK.
